Captain Underpants Theme Song (from "Captain Underpants: The First Epic Movie" soundtrack)

Tra la la!

Are you worried about impending doom?
Those evil villains got ya filled with gloom?
Don't ya fear, there's a hero in the sky! The sky! The sky!

Its not a bird and its not a plane
And its not an egg salad sandwich
Its the waistband warrior
Hear his mighty battle cry

Tra la la!

Underpants!
Hey watch out, Crime!
Its Captain Underpants!
Its wedgie power time!
Na na na na na
Captain Underpants!
Yeah, yeah, yeah!
Faster than a speeding waistband!

Underpants!
He's busting down doors!
Captain Underpants!
While wearing just his drawers
Na na na na na
Captain Underpants!
Yeah, yeah, yeah!
More powerful than boxer shorts!

His name is Under, Under, Underpants!
I'm saying Under, Under, Underpants!
Oh by some unlikely chance
Captain Underpants is his name

Tra la la!

Snap your fingers and he'll be right there!
That freaky bald dude in his underwear
He'll drop his trousers
And fight to save the day! the day! the day!

There he goes in his dashing cape!
Here he comes in his tighty whiteys
All the bad guys soil themselves every time they hear him say
Tra la la!

Underpants!
Yeah, who's that hunk?!
Captain Underpants!
Is that cotton pre-shrunk?
Na na na na na
Captain Underpants!
Yeah, yeah, yeah!

Underpants!
Suspend your disbelief
Captain Underpants
He'll save the world in his briefs
Na na na na na
Captain Underpants!
Yeah, yeah, yeah!

To the skies! Wow!

Under, Under, Underpants!
I'm saying Under, Under, Underpants!
Check out that superhero stance!
Captain Underpants is his name!

Oh, Under, Under, Underpants!
He's Captain
Under, Under, Underpants!
By some crazy circumstance
Captain Underpants is his name

Tra la la!
